Interesting topic. In childhood I always thought the world changed when I changed, making me think reality was not so real. At age 12 I was walking down the blvd going home and suddenly I woke up. It something I've tried to figure out my entire life because every memory before 12 seems like a dream, as if the "real" me was born at age 12. I've asked lot of people if they had this experience or knew what it was. Everyone probably thought I'm crazy. Since learning I have DID it makes more sense. In adulthood life seems like a lucid dream or being awake in a dream. The idea we live in a simulation is also a possibility. It can make life more interesting and adventurous.
